Hatton deserves the credit for stopping him the way he did in 4 rnds. Nobody had ever koed Castillo before.

The thing is Castillo, though trying to fight back as a warrior, looked really slow and sluggish. It only took a minute of the fight and I already knew he wasn't gonna win the fight. I don't know if he was shot or if it was the weight but there was just no way he was going to win. Still the fact that he was stopped early is a credit to Hatton.
